Here’s a rework of my Faceless Dave idea. Added him being difficult to describe and being able to locate things. Might just make him a faceless gentleman again if you guys think that’s better.

Euclid-Faceless Dave: a man of undetermined age who lacks any notable features. seems to not mind and actually enjoys when expressions are draws on him and often (comically) acts out said expression. enjoys "drinking" gin and tonic via unknown means. He has notable persuasive skills, but these do not seem to be anomalous in nature. Additionally, many subject who have interacted with SCP-TBD have found extreme difficulty in describing him beyond, a man with a blank face, being unable to recall clothing, height, or any other features.
SCP-TBD seems to have an extensive knowledge of history including the relative whereabouts of several missing or previously missing objects including the previously lost RMS Titanic, the Irish crown jewels, and Atlantis. Testing has shown that SCP-TBD can reliably locate lost objects such as ghost ships. Testing for more significant lost objects is ongoing.

SCP-TBD is to be kept in standard class-c housing on site – BLANK and permitted class-c clearance. Staff members are to limit visits to an hour and a half and avoid arguments. Any testing of SCP-TBD’s anomalous abilities is to be carried out by MTF Xi – 8 “Cartographers”, due to prior incidents with less experienced staff (see interview 2).

So this is an interesting base for an SCP, but to work as an article it needs more than anomalous effect.

The article needs some kind of story or narrative to keep the reader invested in Dave. I like the missing objects angle, but I think it needs expansion. Why can he detect missing things? Is he looking for those things, or is he looking for his missing face and just so happens to find them instead? Is he missing something other than his face (Like family, or love, or something) and is that what he's looking for?

I think the actual personality of Dave needs a little more work too. How does he feel about his anomalous abilities? Being trapped in a faceless body that no one can describe must be kind of strange. does he want to be normal? Is he proud? Does he like the Foundation? Does he want to escape?

Also, what do you mean "more significant lost objects is ongoing"? The objects he's found seem incredibly significant. Although I like the idea of the Foundation forcing this guy into becoming a sniffer dog for them. Does he enjoy that? Does he feel useful or like he's being used?

I’ll take these critiques and work on my first sandbox draft. And no, he is not actually missing anything as in it’s out there somewhere. He simply lacks a face. I’m thinking of making him an older fellow in terms of knowledge, like a traveler historian. It’ll be implied in ways that he was present for many historical events as well, the earliest being the war of 1812. As for the rest, I’ll have to work that all out in my draft. Thanks!
